Occurs in NE Qld primarily on the Einasleigh Uplands from the Mt Carbine–Mt Molloy region S to Hervey Ra., W of Townsville. Also occurs in coastal areas N of Cooktown in the Cape Melville–Bathurst Bay region including Stanley Is., with a southern outlier near Cranbourne Stn.


Branchlets sometimes +/- pendulous, slender and brittle (snapping with a clean fracture). Phyllodes falcate to subfalcate, often long-tapered at apex, 8–14 cm long, 0.7–2 (–2.5) cm wide, green to pale grey-green or slightly subglaucous, commonly +/- milky green when dry, minor nerves (4–) 5–7 per mm. Spikes 2–4 per axil. Funicle/aril normally to encircling the seed (rarely 2–5-folded as in subsp. disparrima), white (tinged grey) to cream, ageing pale yellow.


Flowers March–June.


Usually found along seasonally dry creeks, diffuse drainage lines or run-on sites along roadsides in rocky, low, hilly or undulating terrain.


Qld: Mt Mulligan, c. 2 km S of Mine Site along pipeline leading to falls on Richards Ck, J.R.Clarkson 5253 (BRI, CANB, DNA, K, MEL, NSW, PERTH, QRS); Hervey Ra., c. 50 km W of Townsville, M.W.McDonald & B.R.Maslin BRM 7627 (BRI, CANB, DNA, K, MEL, NSW, NY, PERTH).


On Stanley Is. near Bathurst Head, subsp. calidestris grows in heath on exposed sandstone headlands where its maximum height is 1.5 m tall.
